NOBLE W. HARTMAN, OF TOLEDO, OHIO.

SANITARY VAULT.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed. January 7, 1904. Serial No. 188,004.

To all whom it may concern:

Be it known that I, NOBLE W. HARTMAN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have inventedcertain new and useful Improvements in Sanitary Vaults; and I do dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to an outside watercloset and vault and its object is to provide an appliance which shall be exceedingly cheap simple and efficient, which shall be entirely sanitary and which may be constructed and installed by unskilled workmen.

A furtherobject of my invention'is to dispense with catch-basins and'their attendant objectionable features.

I attain these objects by means of the devices and arrangement of arts hereinafter described, and shown and 1 lustrated in the accompanying drawings in whi ch Figure 1 1s a central vertical sectional elevation 'of my vault; Fig. 2 a like view of a portion of the same, seen at a right angle to the view in Fig. 1; Fig. 3 an enlarged side elevation of the flushing lever hereinafter re ferred to; Fig. 4 an enlarged top-plan view of the plate and bracket designed for the support of said flushing lever, and Fig. 5 an enarged top-plan view of the adjusting device hereinafter referred to.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a hopper preferably of cast iron. At top the hopper is provided with a flange and shoulder 2 forming a recess or socket for the reception of the lower end of a series of sections of glazed earthenware pipes 3, which extend vertically upwardly to a point above the ground. The bottom of the hopper is contracted and is formed at its lower end to fit into the upturned end of a sewer-pipe trap 4. Through the side of the opper, near its top, is an inlet opening 5 formed as a socket for the reception of the end of inlet-pipe 6 which is connected with the house or kitchen drain, or both, and

descends at an angle as shown. The hopper also has near its top an opening 7, located somewhat above the opening 5. The open ing 7 leads out through a horizontal boss or s ud 8 the end of which fits into the end of an e bow 9 at the upper end of a glazed tile over-,

flow pipe 10. This pipe is connected at bottom with and leads into the trap 4, below the water-level of the trap, as shown, in such manner that the trap forms a seal for both the overflow-pipe and for the outlet-pipe. Over the mouth of the overflow-pipe is a strainer 11 to prevent this pipe from becoming clogged.

Immediately above the upper end of the series of pipe-lengths 3 is a water-closet seat 12. Upon the top and at the rear side of the seat is secured a plate 13 from which springs upwardly a bracket 14. At the front side of the top of this bracket is pivotally supported, as at 15, a bell-crank lever. The pivot-pin 15 is elongated at front, as at 15. (See Fig. 1). One member of the bell-crank lever is extended horizontally as a handle 16. The other member of the lever is pivotallyconnected, as at 17, with a link-bar 18 which at top swings horizontally in a slot 13, in the bracket-plate 13, and which at bottom is pivotally connected with a lug 19 on a sleeve 20, vertically movable upon valve-rod 21. This rod reciprocates vertically in a hole 13 in the plate 13. The sleeve 20 is adjustably secured to the valve-rod by means of setscrew 20 At the lower end of the valverod is a valve 22 which closes the lower end of the hopper 1. This valve is shaped as a double cone, as shown, and is formed preferably of wood,such as red cedar. The outlet opening of the hopper is finished to form a seat for the valve.

The operation of my device is as follows: Assuming that the parts are assembled as shown and described; (the hopper being buried below the surface of the ground some six feet, more or less that the valve is closed with the handle 16 in the position indicated in solid lines in Fig. 2, and that the hopper is full up to the overflow-pipe 10, and that it is desired to empty and to flush the hopper, the handle 16 is now lifted into the position indicated by the dotted lines in Fig. 2. The other arm of the bell-crank lever lifts-the link 18 with its attached valve-rod and valve so that the link strikes the projecting end 15 of the bell-crank pivot which forms a stop limiting the throw of the bell crank lever. It will be seen that the lever cannot be thrown far enough to bring the arm of the lever and the link bar 18 into vertical alinement, and that the weight of the valve-rod and valve is suspended from the lever in such manner that when the lever is released the sus ended weight will invariably automatically c ose the valve 22. The valve being opened the contents of the hopper escape rapidly through the large opening at the bottom of the ho per, through the trap to the sewer. If at tiie same moment a tub of Wash-water be emptied through the seat the fiushin and cleansin of the apparatus will be faciIitated. It wi 1 be seen thatfrom the peculiar shape of the large wood valve 22 it will clear itself at top when raised and when lowered will guide itself upon the inclined sides of the hopper to its seat. The device here described and shown is cheap, simple, easily constructed, and answers all the purposes of the ordinary outside watercloset and catch-basin without the familiar objections and difficulties which are encountered in their use.

.Having described my invention, what I claim and desire to secure by Letters Patent 1. In a device of the described character, a hopper, a down ipe connected to the top of the hopper, a rain-pipe leading into the hopper near its top, a sewer-pipe leading from the bottom of the hopper, an overflow pipe leading from near the top of the hop er to said sewer-pipe, and a valve in the out et at the bottom of the hop er.

2. In a device of the escribed character, a hopper formed of a single integral piece and having a flanged to adapted to receive the end of a down pipe, l1aving also a contracted bottom adapted to enter the mouth of a sewer pipe, having also a side opening adapted to receive the end of a drain pipe, an having a spud or boss adapted to enter the mouth of an overflow pipe.

3. In a device of the described character, a hopper connected at top with a down-pipe, and

at its contracted bottom with a sewer-pipe,

the contracted end of the ho per forming a valve-seat, an automatically 0 osing valve on said valve seat, means for actuating the valve, a trap in said sewer-pipe, an overflow pipe connected at its upper end with the upper part of the hopper and at its lower end with said trap, and a downwardly inclined drain-pipe connected with the hop or below the level of the inlet-end of the over ow-pipe.

In testimony whereof I affix my signature in presence of two witnesses.
